Odd Leak And Smoke!

[rbodor3]

unfortunately I'm gone again, in canada for a couple of weeks. When i get home I'll do the leakdown.

I didn't think about the huge jump in compression from the oil, but you're right, it wouldn't make any sense to be HG or valves with the oil test. Would have to be rings at this point, which is the least convenient of the 3 tasks to do, PITA.

Will do the leakdown though anyway and make sure before I pull the head.

Back in the US finally again.

Waiting to do the leakdown this week, but check it, yo:

oil leak = too much blowby on the head. Had a new IPD Viton cap seal replaced, less oil getting thru, but with my increased boost believe this is the root cause still. Will be welding an aluminum 3/4" NPTF bung on the head to add additional crank venting.

smoke = believe this is condensation. It only occurs in reverse because water buildup in reverse pushes back in the exhaust to a hot spot and burns off more. It's stopped smoking now that the weather is warm.

I have built my custom 3" exhaust with straight-thru cat and straight-thru mufflers (all magnaflow). There's a bad low-poitn in the exhaust where I previously used a band-clamp (not air-tight seal). In November I replaced the clamp by welding in v-bands (now that I have the $ to afford), but this also means that the condensation that previously escaped thru the badly sealing band-clamp joint is tight with the v-band joint. I'm drilling a small hole at the low point today to allow condensation to exit; however, don't expect to be able to make sure this is the problem until it gets cold. Will still proceed with the leakdown because I didn't like my compression #s.
